Patent CA-2145417-A1 (CA)
Title: Method and machine for producing details from a sheet of metal
Inventor: SJOEBERG ANDERS
IPC: B21D28/06
Filed: 1993-10-11
Abstract: A method and a machine for prod-ucing plate components (1) from a sheet of metal (2) which is moved through a press (13) for at least a first cutting opera-tion to be performed to separate the plate components from the sheet of metal and a second cutting operation to separate scrap (27), said press being open with a space (32) allowing free insertion of the metal sheet. According to the invention the me-tal sheet is displaced by means of a feed-ing device (11) between the metal working operations, following a predetermined coordinate pattern and being machined in consecutive y-sections (24, 26) each y-sec-tion (24) being fully machined in x-direc-tion before the immediately following y-section (26) is brought into position for machining, the metal sheet being ma-chined within surface areas (33), each of which has a length in x-direction of at most 30 cm, and is larger than the plate compoment so that a peripheral, unbro-ken scrap portion (27) remains after the first cutting operation. The second cutting operation is performed to sever a scrap portion (27) by cutting at an angle so that a trimmed side edge (28) is formed and at the same time a trimmed edge (35) across the y-section (24). Furthermore, displacement of the metal sheet is controlled by a programmable control unit which also controls the movements of the metal working tools as desired.

Title: Reverse wedge truss-forming wall anchor
Inventor: GIANNUZZI LOUIS N
IPC: F16B13/12
Filed: 1995-04-24
Abstract: A dagger-like anchor drivable into a hollow wall and adapted to receive a fastener screw to hold an object adjacent the wall. The anchor is fabricated from a sheet metal blank, shaped, folded and hardened to define a head having a hole to threadably receive the screw, and a pair of normally juxtaposed flat blades aligned with the hole and extending from the head, the blades terminating in triangular sections coming to a point to penetrate the wall. The blades are each provided at offset intermediate positions with a tab that projects through a complementary slot in the other blade.          When the anchor is driven into the wall so that its head lies against the outer surface of the wall, and the fastener screw is then inserted in the hole and turned to advance between the blades, the screw acts to spread the blades and their tabs apart. This causes the tabs to engage the screw to create within the body of the wall a truss whose base chords are formed by the projecting tabs engaging the screw and whose side chords by the blades, the screw then forming the central strut of the truss. The truss acts as a reverse wedge to enhance the holding power of the anchor.

Title: Carrier with means for partially blocking a bar code
Inventor: WEAVER WILLIAM N
IPC: B65B27/04
Filed: 1995-12-28
Abstract: A novel carrier for carrying a group of items, such as cans, bottles or the like which hold beverages, foods or the like, is made of a plastic material having an opaque strip of material printed on a surface of the carrier.  The opaque strip can be a solid, opaque line or a series of opaque dots.  Each item includes an individual machine readable bar code thereon which is at least partially covered by the opaque strip.  The package has a machine readable bar code thereon which is not covered by the opaque strip on the carrier.  The opaque strip prevents the individual bar codes on the items from being read by a typical bar code reader beam.  The bar code on the package can be read since it is not covered by the opaque strip.

Filed: 1994-08-31
Abstract: The invention concerns a device for peeling elongated vegetables, particularly asparagus. The device has a housing (2) with an opening (4) designed to permit a stick of asparagus (50) to be inserted. Inside the housing (2) are several peeling blades (12, 12') which are disposed at different angles with respect to the opening (4) and which act on the stick of asparagus (50). At least one of the blades (12, 12') can move at right angles to the longitudinal axis (6) of the opening (4) and presses flexibly against the stick of asparagus (50). The blades (12,12') each have a cutting edge (19, 19') at the front of which with inspect to the cutting direction (23) a feeler (20, 20') is located. During the peeling operation, the feeler (20, 20') lies against the stick of asparagus and guides the blade (12, 12') tangentially along the outside surface of the stick (50). The device enables sticks of asparagus (50) of differing diameter to be peeled simply in one operation round the whole of their peripheral area.

Title: Nuclear magnetic resonance technique for determining gas effect with borehole logging tools
Inventor: HURLIMANN MARTIN D
IPC: G01R33/44
Filed: 1996-03-22
Abstract: An NMR pulse sequence technique for use in the borehole environment is provided which uses CPMG pulses according to (See formula I) where j is the index of the CPMG echoes gathered, i is the index of the wait times in the pulse sequence, W i are the varying wait times before the CPMG pulses, and tcp is the Carr-Purcell spacing. Measurements are made of the signals induced in the formation as a result of the magnetic fields to find the spin-echo relaxation time T1. Using T1, the gas effect on formation parameters may be derived. Also, gas saturation and gas chemical composition can be derived. In addition, the diffusion coefficient of gas under reservoir conditions can be more than ten times larger than that of water, making the T2 relaxation time of gas more sensitive to static magnetic field gradients. In formations where gas occupies pores larger than about 10µm, this T2 effect (effect of diffusion on the measured T2 relaxation times of gas) can be used to identify gas even though the tool gradients are not uniform.
